The four day tour will take you through France, Switzerland and Italy, climbing en route famous mountain passes such as the Grand St Bernard 2469m, Petite St Bernard 2642m, Cormet de Roseland 1968m and the Cols de Saises, Aravis and Columbiere. There are also ascents of some, perhaps, less well known cols such as Champex Lac and Colle San Carlo. The four day itinerary allows a total gain of around 10,000m of ascent and descent with an average of 100km or 62 miles per day.

When you mention the Weisshorn, more often than not, people draw a blank. They’ve heard of Mt Blanc, Matterhorn and Eiger. But the Weisshorn, no. This may be due to the fact that it’s not the biggest, it’s not on crayon boxes and it doesn’t have a terrifying north face. Yet if you are climbing in the area, on the Dom, Taschhorn, Zinal Rothorn, Rimfischorn, it is this mountain, with its Himalayan faces, sharp summit and long ridges, that draws your eye and is utterly captivating.
